DETACHABLE HANDLE FOR @RATE-SHAKER BARS.

Application file d Mayl 29, 132,57.v Serial' No. 33,791.

matically locking the same so a'sto avoid accidental. disconnection, at the time of imparting the necessary force required to shake down vthe grate, .especially while the locomotive is inmotio-n. f

Another object is to provide locking: means ior this purpose which is of simple construction, requiring but onel additional part to act in'conjunction with the means now .in common use for connecting `shaker lhandles to shaker bars, and requiring but a minimum amount o-alteration in the members to properly adapt the same, the improved means serving at all times to automatically act when the handle Vis applied, and also permitting the latter to be freely removed from the shaker abar when the aforesaidpart or member is moved slightly, either by haiidor` by the foot oit the iemaii, to unlock the ,members. I

A full and complete understanding of the invention may be obtained from a consideration ot the following` detailed description, taken in connection with the accompanying drawing forming a part of this specification, it being understood that while the drawing shows a practical form of the invention, the' latter is not to be connedto. strict conformity with the showing thereof, but may fbe changed or modified, so long as such changes or modifications-'mark no material departure from the salient features of the invention, as speciiically pointed out in the appended claims.

In the drawing, in. which similar reference characters designate corresponding parts throughout the several iigures1` Figure l is a side elevation of a shaker handle applied to a shaker bar and held in engagement therewith by theimproved locking means. Y

Figure 2 is an elevation of the same, taken at right angles to Figure l, the upper portion of the handle being broken away.

Figure 3 is a vertical-section, taken on the iin@ e-aof iugm@ 2 and looking in the ai;

rection ofthe arrows. n

Figure 4 is a transverse section taken on the line 4 4 of. Figure 8, and lookingA in the direction of the arrows. y 1

The shaker bar Las shown in the drawing, is of the usual type employed on locomotives and in other places, said bar being in the torni of a lever fulcru'med at an intermediate point, upon a pivot pin 2 generally carried by abracket (not shown), or in any other desired manner, to locate the same in proper position relative to the. grate bars to be rock-l ed or shaken. The lower end of the shaker bar 1 is pivotally connected to a rod 3 which extends to the Oi'ate bars, and the upper end of the bar is extended upwardly a greater distance than the lower portion below the pivot, and. is preferably tapered, as shown, and said upper end l is provided, on opposite faces, with transversely disposed 'flanges 5 to providea shoulder on either side, to ai'- yrest the downward movement of the operating handle 6` p ,flanges 5 arel located at lthe proper position lon the tapered,upper end of the bar soy l to contact with the lower end of the en- 'against the side of said handle (see Fig. 2),

the socket being so located in the head as to permit of same and, as will be seen by referi ence to Figures l and 3 of the drawing, the

said head is also offset to one side of the longitudinal axis of the handle, while the socket is in longitudinal alinementk with the saine. This arrangement provides a thicker wall 7a to oneside of the socket and, midway between the upper and lower ends of `the head, there is provided a transverse slot 9 extending entirely through said wall 7 a, said slot being arranged at an angle, the lower, inner end of the same intersecting the adjacent, inclined wall of the socket.

`A locking pin, which may be in the form of avstout bolt 10, is loosely mounted in the y ce CTV

transverse, inclined slot of the head, said pin having terminal heads ll to prevent the same Yfrom dislodgment from its seat in the slot, the heads, which may comprise the head et a bolt and a nut, being spaced suiliciently V from the sides ot the socket as to permit the pin or bolt to slide up andv down in the slot,l

in an obvious manner.

The tree, tapered, upper'end ot the shaker bar l is provided 1n one ot its edges with ,a transverse, horizontally disposed groove the handle rests upon the side iianges or 20v stops 5;

l'l/vhcn the `socket is introduced over the upper' end ot shaker bar, in applying the handle tor use, the upper, adjacentv cornerk of the tapered end 'ot the bar encounters the central'portion of the locking pin, where the same entends into the socket at the lower end oit theslot, and such contact .forces the pin outwardly and. upwardly along said slot su'liiciently to allow thel entrance ot the shaker bar. l/Vhen the handle has been lowered to bring the transverse groove l2 in alinement with the lower end ot the slot, the pin immediately falls or rolls into said groove and locks the head of the handle upon the shaker bar when the operation of shaking the grate may be proceeded with and the violent movements impartedl to the handle as well as the rocking and shaking movements of the moving locomotive,

will tail to dislodge the connection. l'lfhen, however, it is desired to remove the handle which is always done after the shaking operation is completed, because oi'l the restricted space in the cab of a locomotive, it is only necessary to slide the pin or bolt 10 slightly up the inclined slot, when the handle may be easily and quickly removed and this freeing of the pin may be accomplished either by the hand Vor the toot of the l fireman.l l

From the foregoing it will be seen that a simple means has been providedfor securely locking together ther handle and shaker bar ol a locomotive or other similar members, and it should be noticed that exist! ing members ot this-character may, by the mere addition of the inclined slot in the socket member of the shaker handle and the provision of the transverse groove in the proper tace of the upper, free end of the shaker bar, be altered to include the improved locking means, in which event the locking pin may be in the form of the bolt and nut, as stated.

lWhat is claimed isz- 4 l. In combination with a grate shaker bar, a detachable yhandle comprising a handle lever; a one piece` socket member at the lower end thereof' fitting theleiid of the' shakerv bar; shoulders on' the'bar abutting the lower end ot'L the socket meinberrsaid shaker bar having a groove in one face; said socket Vmember having an inclined slot on lone side extending transversely through the same, said slot being closed at its upper end and extending at its lower end into the socket and being in alinement with the groove whenthe shoulders are engaged with the socket and being in alignment with the the slot and engaging in thevgroov'e when ligned therewith to lock the handle to the 2. In combination with a grate shaker bar, a detachable handle comprising a handle leve-r; an open-ended socket member at one end thereof fitting the end of the shaker' bar, said socket member having a transverse, inclinedfslot at one side thereof and'extending at its lower end into the socket; oppo- V site shoulders on the bar abutting the lower end ot the socket member; said bar having a transverse groove aligned with the lower end ot the inclined. slot when the shoulders are eng'ageclwith the socket member; and a bolt loosely mounted inthe slot and partially entering the groove vin the bar to f prevent removal of the handle from the bar. l,

In testimony that I claim the foregoing as my own, I have hereto aiiiXed my sig nature. v ,v f Y WILLIAM RANCE, Sir.v
